BEAM CONSTRUCTION.

Application filed. November 28, 1922. Serial No. 603,753.-

To all whom it may concern:

'Be it known that I, WVALTER I. TUTTLE, a

' citizen of the United States, and a resident stand the conditions ofhard and long-continued service and wear. Another object is to provide aconstruction of the above nature which is thoroughly efficient andreliable in action; another object is to provide a construction of theabove nature in which the parts are compactly and securely held inassembled relation and joined in such a manner as to promote ease andconvenience in manufacture. Other objects will bein part obvious or inpart pointed out hereln after. 4

The invention accordingly consists in the features of construction,combinations of elements and, arrangements of parts as will beexemplified in the structure to be hereinafter set forth and the scopeof the application of Which will be indicated in the following claims.

In the drawing, in which is shown one 'of the various possibleembodiments of this invention,

Figure 1 is an end elevation of a beam, certain parts being cut away;and

Figure 2 is a partial sectional elevation, the section being taken alongthe line 22 of Fig. 1 viewed in the direction indicated by the arrows. r

Similar reference characters refer to similar parts in both views of thedrawing.

Referring now to the drawing indetail and first to Fig. 2, there isshown the barrel member 10 of the beam which is preferably of a hollowwooden type. The construction at: both endsof the beam is substantiallythe same and therefore one end only is shown. Inside the barrel 10 is'mounted an abutment 11 preferably of wood, and a metalor wooden spacingblock 12 may be secured to the face of'the abutment 11. A shaft 13extendingaxially throughout the shaft.

length of the barrel passes through the abutment 11 and the spacingblock 12, and threaded into the latter is a set-screw 30 adapted toengage the shaft 13 and prevent relative rotation between the barrel andthe The shaft 13 extends through the beam head, the construction ofwhich will be later described in detail, and is threaded as n14 toreceive a nut 15 which bears against the'head and draws it snuglyagainst the end of the barrel 10. The shaft 13 may be provided with anend portion 16 adapted to rest in suitable trunnions to rotatablysupport the beam.

Referring now to the construction of the head, there is shown a member17 against which the end of the barrel 10 abuts and WlllCll preferablycomprises a solid circular metal disk having its periphery flanged overas at 18 to provide a belt race. Resting against the metal member 17 isa wooden head member which preferably comprises a plurality of radialarms 19 extending from the center of the head substantially to itsperlphery. The arms 19 are preferably evenly spaced and adjacent thecenter of the'head they are tapered to interfit and,

thus form a substantially solid member.

of the head to its periphery and has itsedge portion 23 flanged over andextending between the ends of the wooden arms 19 and the belt race 18,as shown in Fig. 2. Ex

terior of the metal sheath 22 is a metal member or collar 24 of smallerdiameter against which the nut 15 bears. Rivets, as

25, headed against the collar 24, pass through the head and arecountersunk and headed in the metal member 17, thus securely anddependably clamping the members of the head in assembled relation. Thesheath 22 is preferably of comparatively light metal and, as will beseen, its central portion is securely clamped between the collar 24 andthe wooden head member. Adja- 28 and adapted to project into ,Thus theexterior face of the assembled beam head, that is,.the face remote fromthe barrel 10, presents a smooth even surface. The beam head isparticularly strong and sturdy and yet light and flexible, the

wooden reinforcing arms 19 lending the desired strength and rigiditywithout adding greatly to the weight of the head. At the same time, bythe use ofthe metal sheath 22 the wooden members and their securingdevices are encased and uneven surfaces and projecting parts which mightinterfere with the operation of the beam are effectually avoided. V f

Secured to'the inner face of the head is a projecting member 27 whichpreferably takes the form of a metal cap, as shown, secured to theheadmember 17 as by rivets the end of the hollow barrel member 10. The rim27 of the cup-shapedmember 27 rests against the inner surface of thebarrel 10, which surface may be recessed slightly to receive it. Thus,the member 27 serves to transmit the weight'ofthe barrel 10 to the head,which weight would be carried entirely by the shaft 13 without theprovision of such a construction. 'VVhen these beams are loaded they areoften of great weight and being roughly handled in use there is dangerof the shaft 13 becoming bent and out of true due to too great stressbeing'placed upon it. 'A construction such as that just described, forexample, overcomes this difficulty in a simple and effectivev manner bymaking possiblethe'transmission of a part of the weight of the barreland-its load directly 'to the head, relieving the strain upon the shaft.The strength of the beam and its adaptability to withstand hard usageare thus greatly enhanced.

' It" will thus be "seen that there is herein provided a. device whichembodies the featuresaof-this invention, which device in itsactiouattams the various ob]ects of the mvention and v is Well adapted'to meet the conditions of'hard practical use.
